DETAILED DESCRIPTION

Hereinafter, a preferred exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings as follows.
For reference, among the elements of the present invention which will be described hereinafter, a separate detailed description will be omitted for the elements which are same as those of the prior art, but instead will be referred to the previously described prior art.
As illustrated in FIGS. 1 to 3, the vehicle steering wheel cover assembly of the exemplary embodiment of the present invention characterized in that and comprises: a steering wheel cover 100, a heater (not shown) installed in the steering wheel cover 100, a first electric connecting part 220 connected to the heater, and a second electric connecting part 230 whose one end is connected to the vehicle power supply and the other end is connected to the first electric connecting part 220, wherein the first electric connecting part 220 and the second electric connecting part 230 are connected to each other by means of magnetic force in order to supply power to the heater.
The steering wheel cover 100 encompasses the outer circumferential surface of a steering wheel 10.
The heater is installed inside the steering wheel cover 100 so that the steering wheel 10 can be kept warm.
The first electric connecting part 220 is fixedly installed in the steering wheel rotating part 20 wherein the steering wheel 10 is installed.
The other end of the first electric connecting part 220 is connected to the heater.
In the one end of the first electric connecting part 220, a first power supply connecting portion 223 is formed.
At the free end of the first power supply connecting portion 223, a first magnet 221 and a first connecting terminal 222 are installed so as to be disposed in the both sides of the first magnet 221.
Unlike this, diverse arrangement method can be applied to have an arrangement structure such as a cylindrical magnet encompassing two connecting terminals, or a set of magnet respectively disposed in the upper side and the lower side of the two electrodes, or a magnet disposed between the two connecting terminals wherein two connecting terminals are circularly formed in a way that one connecting terminal is disposed inside the other connecting terminal (disposed as two concentric circles), or the like.
Meanwhile, when electric current flows through the heater a heat is generated therein, and the heater will be operated normally even if the first connecting terminal 222 is switchedly connected during the course of rotating the steering wheel since when electric current flows through the heater a heat is generated thereby, regardless of flow direction, as long as the both ends thereof (of the heater) are connected to the positive and the negative electrodes regardless of their polarities.
The wire portion connected to the first power supply connecting portion 223 is fixedly installed in the steering wheel rotating part 20.
One end of the second electric connecting part 230 is connected to the vehicle power supply, and the other end thereof is connected to the first power supply connecting portion 223 of the first electric connecting part 220. A cigar jack can be the vehicle power supply.
The second electric connecting part 230 can be installed to the vehicle body fixing part 30 by using a tape or a double sided tape or the like.
A cigar jack connecting portion 235 is formed in the one end of the second electric connecting part 230, and connected to the cigar jack.
A second power supply connecting portion 231 is formed in the other end of the second electric connecting part 230.
A second magnet is installed in the second power supply connecting portion 231 at the location corresponding to the first magnet 221.
Unlike the previous description, a magnet is provided to either one of the second power supply connecting portion 231 and the first power supply connecting portion 223, and a substance attracted by a magnet (magnetic material) can be provided in the other one.
A second connecting terminal is installed in the second power supply connecting portion 231 at the location corresponding to the first connecting terminal 222.
The second magnet and the second connecting terminal, and the first magnet 221 and the first connecting terminal 222 are respectively installed inside the first power supply connecting portion 223 and the second power supply connecting portion 231 in a way that the surfaces facing each other are exposedly installed so as to be in contact with each other.
Due to such configuration, as illustrated in FIG. 1, when the first power supply connecting portion 223 and the second power supply connecting portion 231 are being closely approached the second magnet is coupled (connected) to the first magnet 221 by means of magnetic force. Therefore, the second connecting terminal is connected to the first connecting terminal 222, and the vehicle power supply can be supplied to the heater thereby. When the power is supplied to the heater, the steering wheel cover 100 becomes warm, and thus the driver's convenience is enhanced thereby in a cold season like winter.
Further, a coil part 234 is formed between the cigar jack connecting portion 235 of the second electric connecting part 230 and the second power supply connecting portion 231. The coil part 234 becomes elastic due to the shape of a coil.
Moreover, a steel wire can be further inserted inside the coil part for imparting a strong elasticity thereto, in addition to the electric wire connecting the cigar jack connecting portion 235 and the second power supply connecting portion 231. Owing to this, the second power supply connecting portion 231 can be returned more smoothly.
Owing to such coil part 234 the second electric connecting part 230 becomes stretchable.
Due to this, when the driver rotates the steering wheel 10 within a certain angle, the second power supply connecting portion 231 is being stretched so as to follow the first power supply connecting portion 223, and the electrical connection is maintained thereby.
As illustrated in FIG. 2, when the driver rotates the steering wheel 10 in excess of a certain angle, the second power supply connecting portion 231 and the first power supply connecting portion 223 are separated from each other, and after the separation the second power supply connecting portion 231 is being returned to its original position due to the elastic force of the coil part 234.
In addition, a guide portion 233 for guiding the second power supply connecting portion 231, a first stopper portion 232 stopped by the guide portion 233, and a second stopper portion 236 for preventing the second power supply connecting portion 231 from being pulled out in excess of a certain length may be provided.
A ring, through which the wire disposed between the second power supply connecting portion 231 and the coil part 234 is penetrating, can be provided as the guide portion 233.
The guide portion 233 is fixedly installed in the vehicle fixing part by using a double sided tape or a tape or the like.
Due to this, in the second electric connecting part 230, the portion between the second power supply connecting portion 231 and the coil part 234 is slidingly installed against the vehicle fixing part 30.
The first stopper portion 232 can be protrudedly in the electrical wire between the guide portion 233 and the second power supply connecting portion 231.
When the second power supply connecting portion 231 is being returned, it is guided by the guide portion 233, and at the same time, it can be easily returned to the original position when the return is being completed since the first stopper portion 232 is being stopped by the guide portion 233.
Thus, if the steering wheel 10 is repositioned to its original location after it has been rotated by the driver, the first power supply connecting portion 223 is automatically connected to the second power supply connecting portion 231.
The second stopper portion 236 can be formed by fixing the middle portion of the coil part 234 to the vehicle fixing part 30.
The second power supply connecting portion 231 is allowed to be stretched within a predetermined length since it cannot be pulled out due to the second stopper portion 236 fixed to the vehicle fixing part 30 when the second power supply connecting portion 231 is stretched in excess of the predetermined length.
In this way, the vehicle steering wheel cover assembly according to the exemplary embodiment of the present invention prevents twisting of the electric wires connected to the heater even when the steering wheel 10 is being rotated by the driver, and at the same time, a simple structure can be maintained, and the manufacturing cost can be kept low as well.
Further, as illustrated in FIG. 3, in the one side of the handle 10, a switch 210 is installed capable of turning on and off the heater. The switch 210 is disposed between the both ends of the first electric connecting part 220.
As described in detail, although the present invention is described with reference to the preferred exemplary embodiment, it will be apparent to the person of ordinary skill in the art that various changes and alterations of the present invention can be made without departing from the spirit and the scope of the present invention written in the claims described herein below.
